The Mössbauer effect and chemistry. Part 8. The spectra of some bis(NN-dialkyldithiocarbamato)halogeno(nitrosyl)iron complexes

Abstract

A number of bis(NN-dialkyldithiocarbamato)halogeno(nitrosyl)iron complexes has been prepared by standard and new methods. These compounds have been characterised by magnetic susceptibility measurements, and by Mössbauer and i.r. spectroscopy. The application of magnetically perturbed Mössbauer spectroscopy to one example, [Fe(S₂CNEt₂)₂(NO)I], has revealed a cis-octahedral geometry. Other examples have similar quadrupole splittings and hence have this geometry also.
